Forum rules and no-advertising policy

As a participant on this forum, it is your responsibility to know and follow our rules. Please read this message in its entirety.

Board Rules

1. You’re responsible for what you say.
As outlined in Section 230 of the Communications Decency Act, The Chronicle of the Horse and its affiliates, as well Jelsoft Enterprises Ltd., the developers of vBulletin, are not legally responsible for statements made in the forums.

This is a public forum viewed by a wide spectrum of people, so please be mindful of what you say and who might be reading it—details of personal disputes are likely better handled privately. While posters are legally responsible for their statements, the moderators may in their discretion remove or edit posts that violate these rules. Users have the ability to modify or delete their own messages after posting, but administrators generally will not delete posts, threads or accounts upon request.

Outright inflammatory, vulgar, harassing, malicious or otherwise inappropriate statements and criminal charges unsubstantiated by a reputable news source or legal documentation will not be tolerated and will be dealt with at the discretion of the moderators.

2. Conversations in horse-related forums should be horse-related.
The forums are a wonderful source of information and support for members of the horse community. While it’s understandably tempting to share information or search for input on other topics upon which members might have a similar level of knowledge, members must maintain the focus on horses.

3. Keep conversations productive, on topic and civil.
Discussion and disagreement are inevitable and encouraged; personal insults, diatribes and sniping comments are unproductive and unacceptable. Whether a subject is light-hearted or serious, keep posts focused on the current topic and of general interest to other participants of that thread. Utilize the private message feature or personal email where appropriate to address side topics or personal issues not related to the topic at large.

4. No advertising in the discussion forums.
Posts in the discussion forums directly or indirectly advertising horses, jobs, items or services for sale or wanted will be removed at the discretion of the moderators. Use of the private messaging feature or email addresses obtained through users’ profiles for unsolicited advertising is not permitted.

Company representatives may participate in discussions and answer questions about their products or services, or suggest their products on recent threads if they fulfill the criteria of a query. False "testimonials" provided by company affiliates posing as general consumers are not appropriate, and self-promotion of sales, ad campaigns, etc. through the discussion forums is not allowed.

Paid advertising is available on our classifieds site and through the purchase of banner ads. The tightly monitored Giveaways forum permits free listings of genuinely free horses and items available or wanted (on a limited basis). Items offered for trade are not allowed.

Advertising Policy Specifics
When in doubt of whether something you want to post constitutes advertising, please contact a moderator privately in advance for further clarification. Refer to the following points for general guidelines:

Horses – Only general discussion about the buying, leasing, selling and pricing of horses is permitted. If the post contains, or links to, the type of specific information typically found in a sales or wanted ad, and it’s related to a horse for sale, regardless of who’s selling it, it doesn’t belong in the discussion forums.

Stallions – Board members may ask for suggestions on breeding stallion recommendations. Stallion owners may reply to such queries by suggesting their own stallions, only if their horse fits the specific criteria of the original poster. Excessive promotion of a stallion by its owner or related parties is not permitted and will be addressed at the discretion of the moderators.

Services – Members may use the forums to ask for general recommendations of trainers, barns, shippers, farriers, etc., and other members may answer those requests by suggesting themselves or their company, if their services fulfill the specific criteria of the original post. Members may not solicit other members for business if it is not in response to a direct, genuine query.

Products – While members may ask for general opinions and suggestions on equipment, trailers, trucks, etc., they may not list the specific attributes for which they are in the market, as such posts serve as wanted ads.

Event Announcements – Members may post one notification of an upcoming event that may be of interest to fellow members, if the original poster does not benefit financially from the event. Such threads may not be “bumped” excessively. Premium members may post their own notices in the Event Announcements forum.

Charities/Rescues – Announcements for charitable or fundraising events can only be made for 501(c)(3) tax-exempt organizations. Special exceptions may be made, at the moderators’ discretion and direction, for board-related events or fundraising activities in extraordinary circumstances.

Occasional posts regarding horses available for adoption through IRS-registered horse rescue or placement programs are permitted in the appropriate forums, but these threads may be limited at the discretion of the moderators. Individuals may not advertise or make announcements for horses in need of rescue, placement or adoption unless the horse is available through a recognized rescue or placement agency or government-run entity or the thread fits the criteria for and is located in the Giveaways forum.

5. Do not post copyrighted photographs unless you have purchased that photo and have permission to do so.

6. Respect other members.
As members are often passionate about their beliefs and intentions can easily be misinterpreted in this type of environment, try to explore or resolve the inevitable disagreements that arise in the course of threads calmly and rationally.

If you see a post that you feel violates the rules of the board, please click the “alert” button (exclamation point inside of a triangle) in the bottom left corner of the post, which will alert ONLY the moderators to the post in question. They will then take whatever action, or no action, as deemed appropriate for the situation at their discretion. Do not air grievances regarding other posters or the moderators in the discussion forums.

Please be advised that adding another user to your “Ignore” list via your User Control Panel can be a useful tactic, which blocks posts and private messages by members whose commentary you’d rather avoid reading.

7. We have the right to reproduce statements made in the forums.
The Chronicle of the Horse may copy, quote, link to or otherwise reproduce posts, or portions of posts, in print or online for advertising or editorial purposes, if attributed to their original authors, and by posting in this forum, you hereby grant to The Chronicle of the Horse a perpetual, non-exclusive license under copyright and other rights, to do so.

8. We reserve the right to enforce and amend the rules.
The moderators may delete, edit, move or close any post or thread at any time, or refrain from doing any of the foregoing, in their discretion, and may suspend or revoke a user’s membership privileges at any time to maintain adherence to the rules and the general spirit of the forum. These rules may be amended at any time to address the current needs of the board.

  • Any experiences with laser surgery on over grown corpora nigra?

    I have had a full exam done on my horse's eye by a specialist and the conclusion was the new spooking (that has lasted 2 years and only outside on sunny days) is caused by the corpora nigra blocking his vision, leaving two small "pupils" on each side of the c. nigra. This is affecting his jumping career. If only I could make it rain at every show!

    So does anyone have any experience with the laser surgery to deflate the "cysts". If so, where was it done and what did it cost?

    Has any one come up with other solutions to this problem?

    I asked the same thing in the fall with no response. My stallion has cystic corpora nigra.

    He's right on the cusp of being too old to be a surgical candidate... for now, I'm just trying to find more info. There is very little.

    I'm still trying to find out if it's genetic--because he'll get the big snip if it is, even at his age!

      I have sent a few clients for this proceedure - We usually have them go to NC State because it is close and their ophtho service is top notch. I think the cost was around $1000-$1500 for both eyes, but don't quote me on that

      It's performed under standing sedation with a laser - typically they will keep the horse overnight to make sure no problems post op. I think complications are fairly rare. If I find cystic corpra nigra on an exam, I tell people if the horse is spooky I'd have them lasered, if they're causing no problem I'd leave them alone.

      It's a fairly quick deal - I have seen some lasered that don't "deflate" as well as others - not sure why.

        What a timely thread for me!!!! My TB was diagosed this week with corpora nigra cysts in both eyes. My vet contacted UGA vet school and they can do the procedure there. The cost for the laser surgery is $1000-1200. But UGA wants him to stay there for 3-7 days afterwards which will be approximately $1500 if there are no complications.

        My vet is trying to locate another opthamologists in the Atlanta area to if someone else can perform the surgery and then we do the aftercare at my trainer's barn.

        My horse started acting very spooky in the last 3 months and also freaking out when tied up which is why I had the vet look at him.

        My horse is also a headshaker and there is potentially a connection with the cysts and headshaking. My vet has read 10-12 cases studies of headshakers who had the cysts deflated with 100% success of curing the headshaking.

        I had PM'd someone here on COTH who had her horse done a few years ago in Canada and it cost her $1300 CDN. Her horse is back to normal, no spooking or refusals now.

          Oklahoma. Either OSU (90 minutes away) or a local prival clinic can perform the surgery. It would be done by the same ophthalmologist, but I have not yet contacted either for specifics such as price and stay requirement. I wanted to see if anyone else has had an experience with this.

            Did the horses you had sent to NC State need more than one laser treatment to 'deflate' the cysts? Do you know if those horses stopped being spooky and return to their 'normal' personalities?

            I am a little concerned why UGA wants to keep the horse there so much longer than NC State. Could that mean UGA hasn't performed the surgery much?....

              If you find out the details with OSU, I would be interested to hear their stay requirement.

                The horse that I sent recently I *think* is less spooky, but it's hard to tell. At this point she's not really back in "work". The owners had her in pro training, but once the cystic corpra nigra were found, they stopped since we had a potential medical cause for the spookyness. I'll call the owner tomorrow and see what she thinks.

                As far as length of hospital stay, it may just depend on the vet. We send lots of stuff to the ophtho dept at NC state, so they were very comfortable with me doing a recheck at about 1 week post op. I would just ask them why she needs to stay that long. They do prescribe ointment to be put in the eye post op, and they may have had bad experiences with owners being able to put it in.

                As far as the relm of dificulty of what your average vet ophthalmologist does on a daily basis, lasering these cysts is probably pretty simple compared to a lot of other surgery they do.

                  If *anyone* is having a conversation with a vet about this, could you ask if they know if it's genetic or not?

                  I've gotten no answers to my inquiries...

                    I have been told they can be genetic, but it is difficult to know without examining the line of horses. My horse is a gelding so I am not in the same situation as you, but if a stallion I wanted to breed to had them and the mare did not, it would not change my mind on breeding to the stallion.

                      Equus had an article about this, I think last year.

                        N.C. State

                        Well I have scheduled to have my horse's laser surgery at N.C. State on Feb. 11-12th. The evaluation will be on Thursday, Feb. 11th and if all goes well, the laser surgery will be done on Friday the 12th. It's possible my horse will be released later on Friday to bring him home.

                        It's a haul for me to take him there (7 hours) but my vet did some research and spoke to local opthamologists who referred us to N.C. State.

                        My fingers are crossed it goes well and helps him!!!!

                          I know this is an old thread, but can you update please?

                          other than laser surgery, are there any other treatment options?

                            Not the OP, but as far as I know, the only treatment option for corpora nigra cysts is the laser surgery. My horse had it done on both eyes last year and the only option presented to me at the time was laser surgery.

                            They weren't able to deflate all of them in one of his eyes (his were rather large/numerous) but they don't seem to be affecting his vision. So far they haven't come back and (knock on wood) he's doing great (at least when it comes to his eyes!).
